Question

正如主题所说，我的注释Hibernate回调方法在它们应该的时候不会触发。这是我的配置，也许有人可以建议我缺少什么。我试图遵循基本指令here，虽然他们的示例代码中似乎有一个拼写错误（“Audit.class”???）虽然我们没有正式使用JPA注释（而是使用hbm。 xml文件），它们应该仍然可以hibernate-entitymanager正确吗？

Java对象：

@Entity
@EntityListeners(Objectlistener.class)
public class Bannedword implements java.io.Serializable {

    private Date createddate;
    private Date lastmodifieddate;
         /**/
    public Date getCreateddate() {
        return createddate;
    }

    public void setCreateddate(Date createddate) {
        this.createddate = createddate;
    }

    public Date getLastmodifieddate() {
        return lastmodifieddate;
    }

    public void setLastmodifieddate(Date lastmodifieddate) {
        this.lastmodifieddate = lastmodifieddate;
    }
}

对象监听器：

public class Objectlistener {
    /**
     * automatic property set before any database persistence
     */
    @PreUpdate
    public void setLastmodifieddate(Bannedword word) {
        System.out.println("Object listner!");
        word.setLastmodifieddate(new Date());
    }

    @PrePersist
    public void setCreateddate(Bannedword word){
        System.out.println("Object listner!");
        word.setCreateddate(new Date());
    }

}

Bannedword.hbml.xml （我意识到createddate和lastmodifieddate）尚未映射 - 但我认为他们不需要为了触发触发器而触发？

与Hibernate相关的 POM.xml 条目：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-c3p0</artifactId>
    <version>4.2.1.Final</version>
    </dependency>
        <dependency>

       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-entitymanager</artifactId>
       <version>4.2.2.Final</version>

最后是 sessionfactory 的内容，我尝试根据阅读here

添加反思管理器的内容

private SessionFactory configureSessionFactory() throws HibernateException{
        Configuration configuration = new Configuration().configure();
        serviceRegistry = new ServiceRegistryBuilder().applySettings(
                configuration.getProperties()).build();
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);

        ReflectionManager reflectionManager = configuration.getReflectionManager();

//      EntityCallbackHandler callbackHandler = new EntityCallbackHandler();
//      callbackHandler.add(Bannedword.class, null, null);
//      EventListenerRegistry registry = sessionFactory.getServiceRegistry().getService(EventListenerRegistry.class);
//      
        return sessionFactory;
    }

Hibernate Callbacks没有触发
